Arterial wave intensity and ventriculoarterial interaction.
Wave intensity analysis has been applied to the study of arterial hemodynamics. It is a measure of the power transported by waves as they propagate within the arteries and may provide quantitative information about both upstream and downstream conditions. This paper discusses the physical meaning of wave intensity, its measurement using invasive and noninvasive methods, and the effects of physical and pharmacological interventions.
